The Challenge
Scaling Across 7 Clients Without Losing Quality
The agency had grown quickly and was managing SEO for 7 active clients at once, each with different niches, target markets and languages. Its in-house link builder was producing 15–20 links a month in total, far too few to make a difference across 7 accounts.
They needed a fulfilment partner who could: (1) handle genuine multilingual outreach in German, Dutch, French, Spanish, Italian, Polish, Vietnamese, and English; (2) maintain separate publisher pools per client so there was no overlap; (3) deliver everything under the agency's brand with white-label reports; and (4) operate without any client knowing GPM was involved.
The multi-language requirement was the hardest constraint. Many link building providers claim multilingual capability but rely on machine-translated content placed on directories. We use native speakers and local publishers for every language, with the same vetting standards we apply to English campaigns.
- English (UK + US)
- German, Dutch, French
- Spanish, Italian, Polish
- Vietnamese
How We Did It
Separate Publisher Pools. Native Content. No Overlap.
We assigned a dedicated campaign manager to the agency account. Each of the 7 client sites had its own publisher list, curated for that client's niche and target geography. No publisher appeared on more than one client's list, which protects each client's competitive position and avoids footprint issues.
For non-English campaigns, all outreach emails, article briefs, and published content were written by native speakers. We have in-house writers and outreach specialists for German, Dutch, French, Spanish, and Italian; Vietnamese and Polish content goes through vetted freelancers with 3+ years of SEO writing experience.
White-label reporting was delivered monthly: individual site reports branded in the agency's colours, with publisher URLs, DR, organic traffic, and anchor text for each placement. The agency submitted these directly to clients as their own work product.
- Link output increased 10× vs in-house
- Zero client churn during campaign
- Agency expanded from 7 to 11 SEO clients
- Campaign extended to ongoing retainer
